Cadaver Graft in Rhinoplasty, are there any complication using this kind of graft?

Alloderm has been used in rhinoplasty for a long time now with durable results and track record. However, there is always speculations about using cadaveric tissue versus own tissue in the surgical world. The alternative is temporalis fascia graft which can be taken via a small incision on the scalp. There is a fine balance as far as thickness of the skin on the upper portion of the nose. If too thin , the skin can show even subtle imperfections easily, on the other hand, if too think, the skin may look unnatural.

Very thin skin can shrink wrap too much revealing subtle imperfections that would otherwise be camouflaged by thicker soft tissue.  Thin skin may benefit from a tissue thickener, similar to carpet padding underneath the carpet.  If you are concerned about cadaveric tissue using temporalis fascia may be something to discuss with your surgeon.  

Acellular Dermal Matrices (ADMs) like Alloderm are often used as substitutes to camouflage contour irregularities if a patient's tissue is not readily available.  Complications, although rarer, include redness, swelling, infection, bulkiness, and additional contour irregularities.  It may be helpful for you to provide photos so that we may offer the appropriate advice.
